After the test has loaded and displayed, use the following commands to return measurement data:

For the entire Limit Line Test:

:MEASure:LLINe:FPOints? returns the number of displayed failed data points.
:MEASure:LLINe:MARGin? returns the pass/fail margin.
:MEASure:LLINe:MLOCation? returns the time location of the pass/fail margin.

For a selected limit line in the Limit Line Test:

:MEASure:LLINe:LINE:FPOints? returns the number of displayed failed data points.
:MEASure:LLINe:LINE:MARGin? returns the pass/fail margin.
:MEASure:LLINe:LINE:MLOCation? returns the time location of the pass/fail margin.
